Index of column

Does the IndexOf() method from GridColumnCollection return a zero based index?

What will be returned if the column wasn´t found?

Thanks,

Frank

Remark to: http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/columns/reordering

...

GridColumnCollection cols = grid.MasterTableView.Columns;

GridColumn c = cols.FindByUniqueName(columnName);

if (c != null)

...

FindByUniqueName throws a GridException if the column wasn´t found.

So why testing c for null?

Change YAxis Step on client-side

Hi

Is it possible to change the yAxis step client-side?

something like

chart._chartObject.options.yAxis.step = 2;

just after obtain the data.

function setDataFromService(sender, args) {

//Get the returned data

var newData = args.get_content().d;

if (newData.length > 0) {

chart._chartObject.options.title.text = newData[0].Name;

//step Y AXIS

chart._chartObject.options.yAxis.step = 2;

}

else

chart._chartObject.options.title.text = "";

//Set the new datasource to the RadHtmlChart

chart.set_dataSource(newData);

//Repaint the RadHtmlChart

chart.repaint();

//Avoid raising the OnClientResponseEnded client-side event

//avoid setting the received data as content for the RadXmlHttpPanel

args.set_cancel(true);

if (currentLoadingPanel != null) {

currentLoadingPanel.hide(currentControl);

}

[Solved] Filter on a column field with a OLAP connection

hi,

I have a pivotgrid connected to an OLAP cube.
I have placed on the columns fields the Year field and I wish to filter this field on a specific year in Code-behind in C #

I browsed the online documentation and the forum but I have not found the proper use for the methods FilterByLabel, FilterByValue, SetFilterIncludes.
I think that the examples provided are suitable for connections to relational databases but not multidimensional.

Could someone tell me how I can implement that kind of filter.

thank you in advance

best regards

Looks really bad when zooming

Hi,

The color picker doesn't looks good when zooming in the browser.

Try zooming to 120% and run your demo:

http://demos.telerik.com/aspnet-ajax/colorpicker/examples/overview/defaultcs.aspx

You need to reload the page after zooming!

The Web colors wraps, and the HSB/HSV tabs also wraps a lot!

Save RadGauge to PDF

I am running asp.net framework 4.0; Windows 10; Telerik UI for ASP.NET AJAX v2015.2.729.40

In a webforms asp.net project, I have created multiple RadGauges in my C# codebehind, using data pulled from a SQL Server database. Now I need to do one or more of the following:

-save the RadGauges to PDF or as an image file (that can later be emailed)--preferably mutiple gauges per file;

-OR email the gauges

-OR print the gauges

If I can do the FIRST option, I can, obviously do the other two...

I have searched and searched for several days to attempt to do this on my own before sending in a request...and I simply cannot seem to work this out. Can someone assist me? Thanks in advance for any assistance!

RadGridView Column gets removed while drag drop

Hi,

I have a radgridview with a ColumnHeader group.

one of the column header group is pinned.

If i drop a column on the pinned column group header, the column is getting removed.I can not even drag it back from the column chooser

Is there a setting to prevent this from happening. it basically hangs with that column label floating around.
